"I highly recommend Sparks Electric. They recently completed an electrical box expansion, installed two ceiling fans, and replaced two bathroom fans in my home. Blake provided an itemized quote for a fair price before starting the job. His team arrived on time, were polite, and cleaned up after themselves. They also had excellent communication throughout the project. Iâ m very pleased with their work and recommend them to anyone looking for electrical work."

"The furnace took 4 days to get approved( not counting a Sunday) the others were quick but the water heater had to be ordered so without hot water for a week. One ceiling fan was easy but within a year their policy changed and They would not install the one I purchased and had to get a new one approved and then ordered online and took several weeks to get straightened out. Not sure who was at fault, AHS, installer or scheduling with renter. Fee is usually $75 per visit"

Bathroom Fan Installation questions, answered by experts

A small wobble isn’t worrisome, especially when you’re using your fan at top speed, but a significant one is. Ball joint fans, which are used on sloped ceilings, are more likely to wobble than a standard fan based on their design. But even then, you shouldn’t see significant wobbling, as this can be a sign of a bad installation.

If you think your fan needs to be oiled, the first thing that you have to do is cut the power to the fan. The best and safest way to do this is by flipping the circuit breaker that leads to that room.  Depending on the model of your fan, you may need to remove a cover. Look for a hole labeled oil. If there isn't one, check the manual or look for schematics online. Once located, use the recommended lubricant or spray. 

Leaving an exhaust fan on constantly isn’t ideal. While it helps remove moisture and odors, continuous use will lead to wear and tear, higher energy costs, and even fire risks if the motor overheats. Bathroom fans should run for 20 to 30 minutes after a shower, while kitchen exhaust fans should be used only when cooking or clearing air.

Never add oil unless the fan is specifically designed for it. Most modern ceiling fans are designed with sealed bearings that don’t require oiling. However, some older fans may have oil ports for lubrication. If your fan is older and you hear squeaking or grinding, check the manual or the manufacturer’s website to see if oiling is recommended.

WD-40 in its liquid or aerosol form is highly flammable. Using it around live electrical parts, such as a bath fan, can generate fire and a dangerous condition. However, if you follow proper safety procedures, including disconnecting the power to the fan before working on it, WD-40 can help remove some of the grime that builds up in your bath fan.
